Pre-Engineered Thermal Fluid Systems

At Sigma Thermal, we specialize in both pre-engineered and custom-built thermal fluid heating solutions. Our pre-engineered heaters facilitate quick fulfillment, easy installation, and efficient operation. We offer two types of pre-engineered thermal fluid heating systems, the HC-2 gas-fired heater, and the SHOTS electric heater.

Pre Engineered Heaters

Pre-Engineered Heaters

Pre-engineered heaters can accommodate a variety of industrial applications. Sigma Thermal’s pre-engineered designs provide excellent efficiency with minimal maintenance requirements, and they don’t require post-production customization.

Advantages of pre-engineered heaters:

  • Simple, robust, reliable, and compliant designs.
  • Designs ready for procurement and fabrication.
  • A small footprint in terms of both space and energy usage.
  • Integrated temperature control systems.
  • Custom configurations are available.

HC2 Gas Fired Heaters

An array of options are available for the HC2  gas-fired thermal fluid heater line, with vertical up-fired, vertical down-fired, and horizontal unit configurations. We can also produce custom units to meet specific application needs. 

Advantages of the pre-engineered HC2 heater include:

Regulatory Compliance

Our burners meet regulatory requirements for use in harsh arctic, desert, and offshore environments. They also meet low emission requirements set by industrial and government regulatory bodies. The base efficiency is at least 88% on an LHV basis, and units outfitted with an economizer can exceed a 93% efficiency mark. The burners operate with standard or alternative fuels.

Versatile Capacity Range

You can choose the right size and capacity for your needs, with units ranging from 1 MM Btu/Hr to 100 MM Btu/Hr. The heaters have a double helical coil design, allowing flue gas to pass three times along the surface area. Each unit is also equipped with Sigma Automation, our advanced control system.

Low Maintenance Requirements

Our pre-engineered heaters can be installed effortlessly, and they reduce maintenance and replacement demands over the life of the unit. The long, low-maintenance service life mitigates most of the long-term costs associated with other heating solutions.

Insulation

Because of the superior flue gas cooling technology, the internal shell has minimal insulation needs. The exterior has mineral wool insulation covered with aluminum cladding.

SHOTS Electric Heaters

Our Sigma Hot Oil Transfer System (SHOTS) is an electrically powered heating system that uses a circulation heater to distribute thermal process fluids across the heating coil, as well as a low-watt density immersion bundle. Each unit features liquid phase service to 600°F.

SHOTS have the following features and benefits:

  • Available in a range of power sizes from 30 kW to 800 kW
  • Compliance with NFPA 87 requirements and optional compliance with CSA
  • Skid-mounted design with:

o   Control panel and control system with safety interlocks and modulating controls

o   Primary circulation pump

o   Mounted and pre-piped expansion tank (optional)
